Arcam AVR 360 Receiver with Totem Hawks or would i


I recently downgraded to a stereo only system and upgraded to Totem Hawks. I'm currently using an Arcam AVR 360 receiver, which I enjoy but was wondering if it would make a huge difference to the sound if I were to sell the 360 and upgrade to an integrated amp? for example, if I were to get rid of the 360 and buy an Arcam A19, would it make such a difference to justify the cost? Please keep in mind that I don't want to spend more than $1500 on a new amp if I were to go in that direction. Another consideration I had was a Naim integrated amp.

I would greatly appreciate you're opinions on the sound difference of the Arcam receiver to an Arcam or Naim integrated amp.
